The international Organization for Medical Physics (IOMP)

IOMP is charged with a mission to advance medical physics practice worldwide by disseminating scientific and technical information, fostering the educational and professional development of medical physics and promoting the highest quality medical services for patients. IOMP’s objectives are to organize international cooperation in medical physics and allied subjects; to contribute to the advancement of medical physics in all its aspects, especially in developing countries; and to encourage and advise on the formation of national organizations of medical physics in those countries which lack such organizations.

IOMP has Strategic Plan that is going to be updated in every term. The current plan for 2018–2022 is available on IOMP website [8].

IOMP is in official non-governmental organization status with the World Health Organization (WHO) and the International Atomic Energy Agency (IAEA).

IOMP is a member and one of the two constituent organizations of the International Union for Physical and Engineering Sciences in Medicine (IUPESM) – Union Member of the International Science Council (ISC) [9, 10].

IOMP structure

IOMP is society of societies and as such its maintains balanced structure and governance to correspond to the actual relationships at all organizational levels with primary objectives in the fields of international cooperation and advancement of medical physics.


The Council is the ultimate authority of the IOMP. The Council is guided in all its decisions by the tradition of free international scientific cooperation.

The IOMP Council consists of: delegates appointed by the national organizations, the officers, the immediate past Secretary-General, representatives of the Regional Organizations, IOMP Committee chairs, the Editor of Medical Physics World, non-voting representatives of the corporate members and non-voting observers.

General Assembly

The IOMP General Assembly consists of all the members of the IOMP. Its role is to enable a direct dialogue by individual Members with the Council. IOMP values the contibution of every individual medical physicists and therefore the General Assembly is a tribune each member may attend and speak at.

Executive committee

The IOMP Executive Committee (ExCom) is responsible for implementing the decisions of the Council, for performing the operational business of the Organization and for proposing to Council strategies to take forward the objectives of the IOMP. ExCom consists of the Officers and the Chairs of Committees and is chaired by the IOMP President.


IOMP works together with International Organizations such as IAEA, WHO and International Labour Organization (ILO) to strengthen the role of Medical Physicists. As a result, ILO had classified medical physicists as a profession in the International Standard Classification of Occupations-08 (ICSO-08). Medical physicist is recognized as a health professional under International Basic Safety Standards which is jointly sponsored by European Commission (EC), Food and Agriculture Organization (FAO), IAEA, ILO, Nuclear Energy Agency (OECD/NEA), Pan-American Health Organization (PAHO), United Nations Environment Programme (UNEP), and WHO, which is an important reference document for governments for recognition of medical physicist IOMP has formal relations with International Commission on Radiological Protection (ICRP) and a Memorandum of Understanding (MoU) with International Radiation Protection Association (IRPA) [11].

IOMP collaborates with organizations in development of a professional certification system for medical physicists that can be implemented on a global basis.

Recognition of professional contribution

IOMP is a society of societies, and as such we value the contribution of all our member societies for the development of medical physics. Throughout the year the most brilliant minds working in the field of medical physics have voluntarily contributed their knowledge and expertise to grow the organization and for the benefit of the patients and healthcare. To acknowledge their contribution and excellence in the various professional aspects of medical physics IOMP has created a set of awards and honours (Table 1). In 2013, IOMP’s 50th Anniversary turned into a driving factor to set the selection of 50 Outstanding Medical Physicists (Table 2).

Table 1 IOMP awards recipients [12]
Table 2 50 Outstanding Medical Physicists during the Period 1963–2013 [13]

Historical record

Like most, if not all, scientific societies, the IOMP relies heavily on the support of our members to preserve history of our organization. Many members have dedicated their time and effort to advance the goals and objectives of the Organization. To document this support, the History Sub-Committee provides the Historical Data Tables that document the work of those individuals who have, over the years, committed time and energy to make it possible for IOMP to achieve its aims and aspirations [14, 15].

IOMP major activities

IOMP’s activities are not only based on top-down approach but include grassroot actions that strengthen medical physicists globally in handling day-to-day work for patient benefit. IOMP actively promotes the profession by reaching out to all parties at global scale (Fig. 2).

IOMP pro-actively interacts with its members

The International Day of Medical Physics (IDMP) is celebrated every year on November 7th, the birthday of Marie Skłodowska–Curie. It was established in 2013 and celebrated every year since then. It unites medical physicists throughout the world under different activities related to our profession [16]. During the 10 years of its existence IDMP has been dedicated to a number of themes as below:

  • IDMP 2013: Radiation Exposure from Medical Procedures, ask the Medical Physicist!

  • IDMP 2014: Looking into the Body – Advancement in Imaging throughout Medical Physics

  • IDMP 2015: Better Medical Physics = Better Cancer Care in Radiation Oncology

  • IDMP 2016: Education in Medical Physics – the Key to Success

  • IDMP 2017: Medical Physics: Providing Holistic Approach to Women Patients and Women Staff Safety in Radiation Medicine (dedicated to Maria Curie’s anniversary)

The International Medical Physics Week (IMPW) is among IOMP’s newest initiatives that support networking, collaboration and professional development among medical physicists [17]. IMPW was established in 2019 and first IMPW was celebrated in 2020. It was in consideration of various aspects of strength and weakness of international day, and for us IDMP, that IOMP felt the need to supplement IDMP by IMPW. IMPW is held in-between the 2 consecutive IDMPs. While the date for IDMP is fixed on 7th Nov, the date for IMPW happens either in later part of April or in early part of May. Every year ExCom debates and decides the dates well in advance. It provides possibilities by which member countries can organize events in respective cities and country with the objectives: a) of popularizing the profession among other colleagues in the clinical and non-clinical field as also among public, b). of promoting medical physics among physics colleagues to let them know how their students can find a career in medical physics, and c) to let medical physicists know how they can do better in patient care. Organizers are welcome to choose their theme that best suits them locally.

The IOMP School was established in 2016 and its mission is to extend and coordinate teaching activities globally. Since then, IOMP School activities have been organized in connection with major medical physics events [18]. IOMP School promotes education and exchange of professional knowledge between medical physicists with various expertise. Some of the world’s leading medical physicist have delivered lectures as part of the IOMP School programs.

The International Conference on Medical Physics (ICMP) is a triennial event organized by IOMP in collaboration with national and regional organizations [19].

The Education and Training Committee (ETC) of was established during the 7th ICMP in 1985 at Helsinki. First Chair of ETC was Carlos E. de Almeida from Brazil for 1985 – 1989. Present ETC is 11th committee for a period of 2018–2022 and Arun Chougule is Chair. ETC is the oldest committee of IOMP which shows importance IOMP gave to education and training of medical physicists. All the earlier ETC chairs and members have contributed for establishing and the achieving the aims and objectives of ETC.

The main objective of ETC is to advance the practice of physics in medicine by fostering the education, training, and professional development of medical physicists, and by promoting highest quality medical services for patients worldwide. The Education and Training Committee of IOMP is entrusted with development of programs related to education and training of medical physics, promotes internationally sponsored education and training programs, considers applications from national and regional organizations for IOMP endorsement and funding, harmonises and standardizes medical physics education programs, and accredits educational, residency and CPD programs.

IOMP Accreditation Board (AB) was established in 2017 for accreditation of medical physics education programmes, medical physics residency programs and CPD accreditation of education/training activities []. So far AB has accredited 4 Medical Physics education programmes and granted CPD accreditation for 9 educational training programmes. ETC evaluates applications received from organizers of scientific programmes in national member organization (NMO) countries for IOMP endorsement and/or funding from IOMP and provides the report to IOMP executive committee. ETC took the responsibility to compile and disseminate information about the medical physics education program based on the feedback from IOMP Regional Organizations. This information is available through the IOMP website since 2018. Further ETC has organized medical physics education and certification sessions during ICMP’s, NMO, RO conferences and is working closely with the ICMP and World Congress organizers for sessions on Education and Training of Medical Physics. ETC represented on Task group of IAEAs to draft the guidelines for certification of medical physicists TSC71.

IOMP Publications Committee

The IOMP Publications Committee (PubCom) ( aims at providing or supporting appropriate publications as a result of research, education and professional programs of the organization. The PubCom comprises Editors or past Editors of international scientific journals in the field of Medical Physics (MP). In the last several years efforts were devoted to promoting publications in MP via the IOMP Series in Medical Physics and Biomedical Engineering (MPBME), published by CRC Press, and in the recognition and involvement of main journals in MP. At present, after PubCom proposed the Guidelines for becoming a scientific publication of IOMP, seven Journals external to IOMP are scientific publications of IOMP: Physics in Medicine and Biology, Physiological Measurement, Medical Physics, Journal of Applied Clinical Medical Physics, Physica Medica – European Journal of Medical Physics, Journal of Medical Physics (JMP), Radiological Physics and Technology.

They join the IOMP official publication Medical Physics International (, fundamental and worldwide diffused publication of IOMP. Via the agreements with those Journals, IOMP may also indicate members in their editorial board, contributing to promoting their spread and scientific activity. The MPBME Series now comprises 78 titles, with as many as 44 books published in the last 5 years [25]. Sample copies of these publications may be distributed to medical physicists worldwide, in particular in low- and middle-income countries, to facilitate their access to high level scientific publications in MP.

PubCom assists IOMP members wishing to propose publication of new materials in MP.

IOMP History Sub-committee

IOMP History Sub-Committee (HSC) was established in 2008 (during the term of office headed by President Barry Allen). HSC was developed as a Sub-Committee of the IOMP Publications Committee (at that time Chaired by William Hendee). The Description and Charge of the HSC were incorporated in the IOMP Bylaws. HSC main objective includes recognition of the IOMP members who have made major contribution(s) to the IOMP and acknowledgement of the contributions of EXCOM and various IOMP activities.

The founding members of the HSC (2008–2012) were: Azam Niroomand-Rad (Chair); Colin Orton; Slavik Tabakov; Robert Gould. At that period the main tables with contributors to the IOMP ExCom and various committees were composed and uploaded at the IOMP web site. Also, papers were written about IOMP History and published by the IOMP Journal Medical Physics International (MPI) in connection with the 50th anniversary of the Oragnisation. In 2009 interviews begun with distinguished medical physicists. These were normally made during the World Congresses.

Azam Niroomand-Rad continued to Chair HSC in the period 2012–2015; HSC Chair (2015–2018) was KY Cheung; HSC Chair (2018–2022) was S Tabakov. In these periods active members of the HSC were C.Orton and P.Smith (alongside the Ex Officio members).

In the period 2018–2022 the History tables were updated and a new activity related to medical physics history was initiated by the IOMP Journal MPI – Special Issues on Medical Physics History—an activity edited by S. Tabakov, P. Sprawls and G. Ibbott, which attracted many eminent medical physicists. These took part in the preparation of 6 Special Issues.
